Byzantium

Greek / Hellenistic culture, Roman state traditions, Oriental influence and Christian faith, together with a relative unity of language and culture, constitute medieval Byzantium. The starting point of Byzantine history is usually taken to be the reign of Constantine the Great (306–337) and the foundation of Constantinople (330). The "east-Roman" or late antique era of Byzantium begins at the latest with the division of the Roman Empire into a Western Roman Empire and an Eastern Roman Empire (395). This "early Byzantine" period lasts until approximately 641. Emperor Justinian I (527–65) reconquered Italy, north Africa, and southern Spain, but after the expansion of Islam (634/98) a reorganized Byzantium, now based on administration by Themes, was limited to the Greek-speaking regions of the Balkan peninsula, Asia Minor, and southern Italy; Latin was abandoned as the language of officialdom. This may be perceived as the "end of antiquity," and the beginning of the "middle Byzantine" era.

This was also the era of Iconoclasm (717–843) and of the origin of the Holy Roman Empire (800). Under the Macedonian Dynasty (10th–11th centuries) Byzantium regained power against the Islamic and Bulgarian states, but the death of Emperor Basil II marked a turning point, with Byzantine power in Asia Minor and southern Italy suffering from the Battle of Manzikert (1071) and the rise of the Normans, respectively. A certain stability was achieved under the Comnenian Dynasty, at least until the Battle of Myriokephalon (1176). Internal conflicts facilitated the sack of Constantinople by the Crusaders (the Fourth Crusade, 1204) and the establishment of Latin states in the south Balkans.

The late period of the Byzantine Empire as a small state begins with the Palaiologos dynasty, which was particularly threatened by the advances of the Ottoman Empire and the economic influence of Venice and Genoa. An empire weakened in part through civil war suffered a severe blow when Thessalonica was captured in 1430, and finally fell to the Ottomans (Fall of Constantinople in 1453, and of Mistras in 1461). The Empire of Trebizond (1204–1461), founded in the wake of the Fourth Crusade, also forms a part of Byzantine history.
